介绍一种新的表面强化方法,即高频脉冲电弧表面强化技术.以碳钢为基体,研究了渗铬强化层近表面的铬浓度变化、强化层相组成,分析了电极材料中碳和空气中氮的迁移现象,并对强化层做了耐磨性实验. 介绍一种新的表面强化方法,即高频脉冲电弧表面强化技术.以碳钢为基体,研究了渗铬强化层近表面的铬浓度变化、强化层相组成,分析了电极材料中碳和空气中氮的迁移现象,并对强化层做了耐磨性实验.
A new method of surface strengthening, namely high frequency pulsed arc surface hardening, is introduced.With carbon steel as substrate, the change of chromium concentration near the surface of the chromizing strengthened layer and the phase composition of the strengthened layer are studied. The carbon and air in the electrode material Medium nitrogen migration phenomenon, and the wear resistance of the reinforced layer was tested.This paper introduced a new surface strengthening method, that is, the high frequency pulsed arc surface strengthening technology.Taking carbon steel as the matrix, Chromium concentration changes, strengthening the phase composition, analysis of the carbon electrode in the electrode material and nitrogen migration in the air, and the reinforced layer made of wear resistance experiments.
